I dont think its at all poss to make it payout other coins... Am totaly guessin that the game rounds off the wins to the nearest £1... And if ya ava luk inside the machine is they any room to fit another hopper next to the £1 Hopper..
Also it will need another hopper psu/mob/board... Am just guessin thou...
Just looking at your post and am guessing your meaning,
the machine/cabinet Size of B3 machines..? Or stake/jackpot of B3 machines because both are many various sizes...

Bellfruit (many) the Eclipse - 1.8mtrs tall / (finger traping) 71cms wide & about the same in depth / weight 108kg (trust me feels more)
Barcrest Gensis - more in weight even though its
Height is only 168cm,less width & depth at 68cm
Casino cabinets various sizes.. Give & take for extras maybe on top or large base most 190cm
