Myclone head on Laser Magnus?

been wanting to pick up an ehobby Ultra Magnus, but the head throws me way off. I mean, sure Magnus has a Prime head at the core anyway, but it's too similar to the Scourge look... for me at least. initially i wanted something like the first few Magnus customs [ehobby Magnus with added G1 Magnus parts].
however, this recent Japanese custom [without the G1 Magnus parts] had just the look that i was after, all with just a [scratchbuilt, apparently] new head.

Since I know nothing about sculpting from scratch, I was wondering if a Myclone Magnus head would work. i was thinking it might be too big. or would it? sadly I only have RiD Scourge and no Myclones to test the size against. Any feedback on this would be appreciated. Thanks!
