Go with two .26 four strokes or two .20-.25 OS FP or LA engines instead.
The Robart system is bulky/heavy in general.
I thought .30 wankels would be good choice if noise is not taken into account. According to label on kit package: engine size .25-.40, weight 3.8-5kg. You have build your plane nicely below the range, exellent.
The kit and engines have travelled together since early 80's so I really want to join them. I have time to think because previous project is still occupying my build table.
