If you want a full frame hobbyist's camera, I have only one recommendation.
The Panasonic Lumix S5.
The S5 is FF, 24mp, has good video and the IBIS is very good. It even does the high-res sensor shift thing Olympus did first on MFT.
Panasonic has taken what they themselves have learned in MFT and they have implemented it well into a body that is both very affordable, not too heavy and is satisfying to use.
Unfortunately.... Panasonic autofocus struggles in continuous modes and can be weird in video too. S-AF works perfectly fine though and Panasonic has good colour science too. L-Mount isn't a baren landscape, mind you. Panasonic make some nice f/1.8 primes which don't break the bank, and if light and compact lenses are more your thing, Sigma make a bunch of lenses in the I-Series - compact primes that are between f/2 and f/3.5. Maybe not the fastest or the most toneh... but they do something most lenses these days don't do - they embody an era of photography from the 70s and 80s with small sizes, less common focal lengths and full metal construction. While these lenses are available on Sony too - they're designed for L-Mount first and foremost.
I'd recommend keeping the Olympus and if you feel the need for FF, then obtain the Panasonic.
Me? I'm sticking with MFT, but every so often I do think about the Sigma fp L - it's particularly high res and features phase detection AF. Plus, Sigma's colour science is driven by its knowledge of how to make bayer sensors look almost like Foveon... almost.
Here's another 40-150 f/2.8 shot.
