Im looking for more on plywood and building some support and then painting some vertical shiplap to the back and sides i agree corbels are usually ugly and not looking to do that

Best to post a measured diagram to see if there's sufficient walkway space for seating. 84" will give adequate seating for three seats (min is ~24" seat, though 30" is better). You'll want 45-60" space from the counter where people will be sitting to allow for movement in that space behind them. That very large overhang will require specialized support as DeWayne notes as it's a safety and injury issue if support is not well-planned and well executed.

IMO even a1 2" overhang should have support often.

Will the floor go under the cabinets?

how "worth it" are the existing cabinets? for the work of this.....is it possible that getting a new island w cabinetry that coordinates w the perimeter might be a good thing to look into? You can get drawers/better glides/ furniture looking feet etc.....Islands in kitchens have not gone out of style and wont in the future.....depending on the overall situation of course [ dimensions of aisles and seating capacity etc] Showing a picture of the space might assist with good suggestions.

can you use the side, as shown here, for a seat.....if you start from scratch as opposed to using the existing, you can save money in a couple ways....... for example Ikea block tops are not expensive...you can get RTA and paint if you have some time and space to set up....or get nice quartersawn oak w clear top coat only...

Can it be done? Probably, other folks have converted islands before.

DIY? Possibly, depends on your skill levels. Inexpensive? Probably not so much. You will likely need to deal with some new flooring to account for under half the island being removed and leaving that footprint open. As Dewayne explained, there is some carpentry work involved in creating a structure hearty enough to support 24 inches worth of counter, including removing the countertop. It's more than just put a piece of plywood under there with some sort of supports and call it a day.

I plan to do a complete gut renovation sooner than later. So I am not looking to add new cabinetry/countertops to endup in the landfill and to do it as economical as possible and be able to better enjoy the space.

Is there a reason you haven't posted photographs?

“Is there a reason you haven't posted photographs?”

Or the measured floorplan, that’s been requested?

Because measurements of the island are listed. I have the space behind its a question on how i can transform the 48” wide work island to be an island that you can sit at… so do you have any ideas on how i can support the countertop if i got rid of the 24” base cabinets - so building something that is 12” deep or a leg support etc is the ideas im looking for.

DeWayne gave you the answer a week ago:

You will need to create a table underlayment with posts, stretcher bars, and steel supports. If stone is on the island, this is much too risky for you to even attempt in place. If you are replacing the island counters, then you need a period of them being removed to work on the carpentry before the new counters are installed.

You're looking at 2+ feet of unsupported overhang. Legs are not enough, especially at that length -- you need metal bars that extend from the tops of the cabinets across the space to the legs, and ideally even more bracing structure. If you were doing it from scratch, it would be a big project, but trying to do it after the fact is asking for somebody to get hurt. Either find a real structure expert, or consider, e.g., keeping the cabinet boxes and just letting people dangle their legs in there. You can also talk to the people at CounterBalance and see if they would recommend using any of their brackets for your application.

This is neither inexpensive nor DIY friendly when you are dealing with an overhang like that. Leave it as is until it is time for that full remodel.

You are going to get yourself unalived. 24” of overhang is huge and very heavy.
