[JB] Axiom Pro 9 RVX purchase

[Trek203]

I am looking at moving away from a different Fishfinder system to Raymarine.

Currently I am considering purchasing the following to replace my older setup:

Axiom 7 E70363-00-NAG
Front mount kit 7" A80498
axiom pro 12 RVX E70372-00-NAG
Front mount kit with cover - 12" A80501
CPT-100 DVS Transducer A80351
CPT adapter cable a80490
Raymarine RV-312 - dual trans T70320
HS-5 SeaTalk Switch (network) a80007
eth 1m A62360
eth 1m A62360
ethernet 20m ethernet 20
radar T70243

This is on a 2002 Triton 2690 with Twin Yamaha 200's.
Normally it is trailer ed.

Instead of the RV-312's, could I use two of the
Real vision transducer RV100's ? A80464, and "Y" them in, or will they not work together.

Please note any other items I might have left off to make this system work.

(edited, to correct part number for the RVX 12", i had the chirp ONLY version, incorrectly)
