I love teh Kohler water tiles because they are flush but if your looking for some off the wall bodyh sprays with 2 spray modes (might even be some with 3), I like the looks of some Grohe ones but I got some Hansa dual mode body sprays. Hansa is a german brand but they are part of KWC which is s swiss brand (go figure). I only went with them cus I had some other Hansa stuff and so when I saw Hansa body sprays just went with them before doing more searching and finding the grohe ones that i liked the looks of better and were cheaper (usually grohe is the most expensive so I'm still having buyers remorse that I found something mroe expensive then grohe) but was already too late so I hope we like the Hansa ones. unlike the water tiles, luckily off wall body sprays are mostly all seem to be the same connection so you can just unscrew them i believe and put on new ones so worst to worst if we dont like the Hansa ones, we can sell them and get different ones. I'm sure the german built and quality will be you get what you pay for (i hope) But yeah Kohler also makes some off wall sprays and I think the master shower kohler bodys prays there is a 3 spray mode version though kinda pricey. There are lots of body spray makes, just try to find reviews and go with ones you also like the looks of. I'll let you know how the Hansa ones work. They are probably great, i just like the looks of the Grohe ones better. Also sounds like you the op are looking for strong ones to get a vigourous massage from them. Thats going to depend on water pressure so something you may want to look into which I am as well that many ppl do use with a shower with a lot of sprays is a water pressure pump to increase water pressure. i have found one that seems to be good and will do the job but still hoping to find some more and get a definitive answer on a water pressure pump that would be good to increase pressure enough for 8 body sprays and 2-3 shower heads if having the pump feed just that bathroom.

You might want to post in Bathrooms. Most people don't install body sprays, but I bet you'll have better luck in that forum.

I have a pattern for Good Morning Sugar Britches. I think it is 19" also. Both arms and legs are jointed. I also have one for Cuddles. I'm not sure how big it is but a little larger, also with jointed arms and legs

Batteries: If the batteries have never been changed, those are probably at end of life. Its a 10 yr old car. Installing new batteries may not make economic sense. The car has 150,000 miles on it and the engine could be at end of life. Replacing the batteries would be putting a large amount of money into a car whose engine is near its end, there fore, to recoup the cost of a battery pack, one may need to also install a re-manufactured engine. You'd end up with a cost that exceeds the purchase of a different vehicle; You'd have a refurbished engine and battery pack in a car with a worn transmission, running gear, and steering parts, and a worn driver's seat, not to mention body corrosion. Because of high mileage, for this purchase to make sense, the seller would have to nearly give the car away. If you want it and its free of corrosion, and the cost is low enough, you might consider it, otherwise look elsewhere. Beware that it may need an engine and battery pack replacement in the near future.
