RH is a hydraulic governor. RE is electronic governor.
Regarding RE, In full sized trucks they were used from 1996 to 2007. Either as 46/47/48 depending on engine size.
The RFE I believe had a stand alone controller where the RE was controlled by a PCM.
On RE versus RH - the output shafts differ, the RH has provisions for a key way and governor support with tubes that the RE does not have. So to your question, if you installed a RE housing you would have no governor assembly.
Using a manual valve body would allow you to use any OD unit. A true auto valve body would need a governor "system" - either the electronic governor or the true hydraulic governor.
I have to imagine taking out a RFE and installing something jury rigged is going to leave a CEL illuminated on the cluster.

A properly built RFE will live if you get the earlier converters out of them and replace them with a good - very good aftermarket converter that has the phenolic stator puck replaced with a billet puck. I can fail a production early RFE converter in 5 minutes if I want to, you can too.
The basic architecture of the 545 is the same as the 64/65/68 RFE design except for size of components in the geartrain.
But only real serious power and weight screws up the 545 once you have a good converter in the box.
