I inherited "Baby" when Pop passed away, and although I've been playing her at home, I don't see myself gigging with a left-handed axe

and I'd really like to keep her in the game if at all possible.
Can anyone tell me what's involved in converting a 1939 Mittenvald from left-handed to right-handed, or if it's even possible without removing the top and spending HUGE bucks?
I know I'll have to replace the bridge and nut, and there's a possibility that the fingerboard may have to be re-contoured. But, what I'm worried about is the bass bar; right now, both the bass bar and sound post are "reversed."
If y'all think such an adventure has a chance of succeeding without breaking the bank, I'll hunt down a local luthier (or take it up to L.A.). Recommendations are welcome.
Thanks in advance for your help.
