Sure, we did this in a house (that we have since sold). I designed it and I loved it. We didn't have room to have the big kitchen we wanted PLUS a standalone table, but did have room to make the island bigger with seating. We also had a separate dining table. We really enjoyed this set up (and didn't use the dining table unless we had extra people visiting). We had no problem with the counter height, though my elderly father did not like it. Also, it was admittedly a huge pain for the period my son was in a high chair because there are no chairs that tall. We still had plenty of room for island storage and didn't need any more kitchen cabinets. In fact, if we wanted to fit a table in the room, we would needed to cut out some cabinets. This allowed us to maximize cabinets. We're currently designing another kitchen for our other condo, and also struggling to fit all of the cabinets I want plus a table. The island seating is the perfect solution. I also really liked sitting at that island while my husband cooked and vice versa. Much more casual and intimate than sitting at a kitchen table. Here's a picture from the mls listing (ignore the wide angle lens :)

Thanks. The Stickley does have an old school library feel, so it really does work nicely in there (I'm on the west coast so Arts & Crafts is as old as public institutions get!). I currently have an old round metal patio set indoors while the backyard is under renovation and I'll have to say, not any table will look right! The umbrella hole is weird. :)

Definitely something white with that table otherwise it’s not only going to be too much wood, it’ll be too dark. The white/off white will be great. Same thing with lighting above table...no black metal imo it’ll be too dark. I’d stick with nickel/silver/steel or even gold/brass

If the fixture isn't part of a collection such that you can buy different variations on a theme easily, I find it's best to at least stay with the same manufacturer so that the finishes match. "Gun metal" and "coffee ombre" are going to mean different things to different manufacturers and in fact may not exist with other makers. But if the fixtures are far enough away from each other that no one can really make a direct comparison you can get close but not match and no one will notice. I think @acm has provided you with some good options that are thinking outside the box a bit.
