Yes, HB, that's how the late 'General' got his marching orders.
It still amazes me that Sherman related topics often end of thorny. I don't get it. It's just a model making theme, after all. Personally, I'm no fan of the tank- despite the contribution it made. I'd rather research, and build, a Centurion or Comet (as I'm doing).But that's just my opinion. Chaque a son gout...
HB, here are some pics, purely for comparison purposes. There's a partially complete Firefly based on Dean's amazing work. It's certainly rich in detail and texture
Next to it is the HL 105mm
If you wanted a Firefly with passable detail, you'd need a to cut a rectangular hatch in the HL turret, and dremel other bits off....and so forth. The split hatch cupola, is available in metal ( I got one from Forgebear, I think) Fabricating other bits from styrene and Milliput would certainly keep you busy. The battery box would be quite easy to make with styrene amd Meng nuts.... and so on. Of course, you already have the barrel. Sometime in the distant future, I intend to make a IC Firefly using most of Dean's kit, and this donor 105. It won't be a TOTM. But won't remain POTM (Parts of the Month) I'm sure you could do a bonzer job with one, but yes, you could expand Mick's growing emporium. For my part, the only aim to create lively debate. Hope the pics give you some idea of the potential task ahead. They were taken in poor light conditions, so lacking the crispness I like to aim for.
