Yes, it's been done. I grew up on Long Island where we had basements and plenty of room. I had O gauge. In my 30s I wanted more scale realism and switched to HO for a few years. In my 40s I discovered G and fell in love with it. When I moved north of New York City for my job I didn't have room for G. After much thought and evaluating possibilities in different scales I decided on N. That was in my 50s and lasted until I was 64 when N became too small for me to work with. At that point I completed the circle and returned to O gauge.
Are you considering 2 rail or 3 rail O? 2 rail generally requires larger curves and so needs more space.
