Answer:  No.  The F11 and J11 chips are wildly different.  If you could
scrounge a Pro380 system board, you could probably replace the 350 system
board with that.
 
IMHO, having a 380 doesn't give much additional return.  Oh sure, the chip
is much more capable than the F11, but with super mode, I/D space, and
cache permanently turned off, what real gain is there other than a little
bit of CPU speed?  I find the stupid disk controller in my 380 to be more
of a problem in throttling the performance of the system.
 
BTW, DEC did once put up genuine RSX-11M-Plus on the 380.  The conditionals
are still there in the Exec source to make it work.  Haven't got around to
trying it yet, but one of these days ...
