Semi hollow solid body and feedback???

If I were to make a semi hollow or even completely hollow "solid" body electric uku would I be dealing with feed back issues. I would be using an under saddle misi pickup for it. I know a lot of solid bodies are chambered out but rarely do you see the f holes cut out in them. So would it be possible and if so should I hollow out all of it or just make it semi hollow.

Nobody has any idea?? Thoughts?? Concerns??

I've used a bunch of inexpensive rod piezos for my projects, so you should be fine with a MiSi. They are really popular for acoustic ukuleles.

Here a good video about uke pickups:

Let me also add I'm gonna be trying hook this thing up to full blown guitar amp and maybe some pedals which was why I was asking about the feedback.
