The Inlet manifold to hold it will be the challenge
If you can mount is similar to the mini ones and
use a spacer to have the charger centrally located
you can use a sidedraft SU or similar with good
clearance to the towers.
The one below has a massive awkward inlet manifold
which could be made way more compact and simple.
