Transom rebuild

Hey everyone, I recently traded for a project boat, 1990 Hydra Sports 2500 CC. Some one else has started to do the repair and stopped. The cut out the transom. From the rear skin, had most of it cleaned up, then they found out it was too much of a project!
I am looking for advice as to the resin I can use. Here are a few pictures

 

My question is can I switch to VE on the inside of the transom ? The outer repair was done with epoxy. Thickened epoxy with cabosil and 1/4 fibers was smeared in the saw cut then while wet 2 layers of 1708 and 1 layer of 1800(no mat on 1800) there was squeeze through at saw cuts to the inside, but that would be the only epoxy, a thin line after grinding it smooth. I have 5 gallons of US composites VE I would like to finish up with for all inside work.

VE on the inside is fine.

 

Thank you for your input!

 

A couple more questions....
This will be my second transom rebuild, but first using VE, the other one I used epoxy, so there was no need for csm.
I was thinking I would do a layer of 1708 over the inner surface of the outside skin to help tie the cut out skin back to the hull, then skim that new layer of cloth with thickened resin to bed new plywood core into. More thickened epoxy between layers of core then, fillets with thickened resin.
1 layer of 1708 on core, extend 12 inches on sides and bottom for tabbing. Next layer of 1708 same size as transom. Tab with 12 inch wide 1708 6 inches on hull/floor 6 inches on transom. 2 more layers 1708 on transom then tab with 8 inch 1708 4 inches either way.
Does this seem right?

 

I am hoping to start fitting core tomorrow and get thus transom back together. Got it 90 percent cleaned up today. Have to find my finger sander to get into the corners good then I can get my pattern made.
