Question: How to change Variable to Fixed Channels and use two Power Supplies

First model train and using MTH HO DCS exclusively.

Reference Barry’s DCS Companion 3rd Edition.

Page 57, 3rd Paragraph from bottom suggests that “Variable channels may not use DCv and is not suitable for MTH PS3 HO.”

Question: Is that true when a Variable Channel is changed to Fixed Chanel?  That is, if I change both of my TIU Variable Channels to Fixed Channels can I use 18vDC in/out as in normal Fixed Channels 1 &2?

Page 67 shows a Geographic Track Block Diagram powered by all four TIU Channels. 

Question:  I have two DC power supplies with adjustable DCv and Amp controls VOLTEQ 1810HD (http://www.volteq.com/volteq-v...-1810hd-18v-10a.html ).  I can set both power supplies to 18volts DC at 10amps and monitor their outputs with DCCSpecialities RRampMeters.  Can I use one power supply for two channels, Variable 1 and Fixed 1, and the other power supply for Fixed 2 and Variable 2 (BOTH VARIABLE Channels 1 &2 software changed to FIXED Channels 1 & 4)?  Do I need to be concerned that a locomotive, crossing from one block to another, might cause “bridging” between power supplies and result in a disaster?  I will also have DCCSpecialties PSX Circuit Breakers between Power Supplies and TIU inputs.
