Add counter rotating engines and propellers ??
I don't think these little $43 engines come in a counter rotating version and RCCA Combat Class 2948 requires MA 8x3 props on all .15 size engines which only come in one version.
I really don't think it is needed as I have flown it with one engine successfully.

Do you have a picture that shows fuel tank placement?
There are no fuel tanks. I run bladders on all my combat airplanes......bladder compartment is under wing saddle area in the wing and can be seen in the pic above of the wing before covering
