The conversion would prolly be too intensive.
For both VE-1 and VT-1:
Wings
Heads
Cockpit + Canopy
Chestplate
Then fastpacks....
Legplates
FP Front for the Elint
Completely new backunits for the Ostrich
Mounting unit + extra thruster for back-unit
A way to lock the Back Unit down, with FP's on, Using the Canon mounting position (Vertical Stabiliazers extended), all while maintaining durability and poseability.
Oh..I forgot the whole freaking Radar Suite for the Elint O_o
I guess if you kept the VT-1 Canon and unable to goto Battroid, it'd be possible to worksomething out, but if you made them transform you'll need some way to get that integral heatshield in.
The mere weight of all that resin would prolly turn your VF-1 into a floppy mess over time.
Then add to that, cost :0 the 1D alone was 80, this much more intensive mod would prolly go a lot higher, say, 200-250
