The simple answer would be no. The adapter plate and the rearmost transmission appear to be for a 235 and an early Powerglide.
It's questionable that the adapter could be used with any later transmission.
The other transmission appears to be a later unit which possibly could be used with the proper adapter. The flywheels and clutches would be of no help for any automatic conversion.
