Keep it simple. Stick with the single engine up front but switch to something a bit larger like an R-2600. I remember one of the guys over on What-If (Liegh Eaton) built a very much modified T-28 with larger engine (might have been an R-2800) that was almost too large for the ariframe. He adorned the wing with about twice the number of stores pylons and some in-the-wing guns. It was rather menacing at first glance.
Otay, late to this but an 18-cylinder R-2800 is
dimensionally smaller than a 14-cylinder R-2600. The P&W lump
was actually rather compact.
I've posted these links before (multiple times on this and other forums, not that it's done much good

overall lengths quoted are
installed lengths, which means it includes things like externally mounted
two-stage intercooled supercharger/turbocharger systems. An aircraft like the T-28 could easily mount one of the
basicR-2800s without major changes to
external appearance, which is great from a modelling standpoint. Yes, a
real worldversion would require major changes for weight and balance reaons, but these would not be
externally visible.
Seriously folks, the real world data is out there and easily available in this digital age, so why not use it?
