It's possible but it's likely to cost you a good bit more than the equivalent DTH bodies and they will be considerably bulkier than the bodies, whether they will require the bonnet to be cut is hard to say and whether they will clear the chaisis rail isn't possible to assess without an attempted dry run installation.
DCOE approx installation costs £1600 + the cost of filters, hosing, trumpets, banjo connections, fuel pressure regulator, throttle linkage etc., I'd say well over £2000.
DTH approx installation costs £1200 complete with airbox, trumpets , linkage and everything you need.
It would be a mistake to compromise the engine for purely aesthetic reasons IMO.
The induction noise on DTH throttle bodies with a decent air filter etc is absolutely brilliant. I just posted this on the air filter thread but gives an idea of the aesthetic...I think they look great as well as work and sound awesome.
