I don't think it will fit; it looks like the 3u bar is meant to mount onto one switch with a pair of 2u stabilizers, and wouldn't line up correctly stradding three switches like you have here.
You would need something like a 3u point-of-sale (POS) keycap (if those exist) - POS caps are designed to straddle multiple switches without any stabilizers.
jkrkvldI have this keyboard from the previous run and I can confirm 3u caps work on this layout. I was using DSA but unsure if that matters.
Note: it will be a HEAVY actuation because you're pressing 3 keys simultaneously
