Indeed - that was a one-off trial from 1944 with Boulton Paul turrets/barbettes each with twin 20mm cannon:

kit': The XA-38's central station fire control system (GE Model 2CFR21B3), upper (GE Model 2CGD50URC1) and lower turrets (GE Model 2CGD50LRC1) were identical to those installed in the A-26 ... and, thus, those turrets were all variations on the B-29's 2-gun units.

Avenger powered by Pratt & Whitney XR-4360-10 28 cylinder four-row

I would expect the lower cowling might be faired in a little more a bit like the original design.  Even noting that the XR-4360 was a bigger engine than the R2600.

I am affraid I do not see your point In my design, below cowling is an ait intake.

I think that Greg was suggesting that your new cowling for the larger R-4360 may not have been ideal.  Since the original R-2600 being as large as it was in diameter there was a lot of room within the cowling that could have been retained for the R-4360 accessories and such.  The only real change would have been in the overall length of the cowling to accommodate the longer R-4360 while the area underneath the engine would have been allocated to engine air intake, oil coolers, and associated components of the engine exhaust. 

I thought I was being edgy and over the top in wanting to build an Avenger powered by an R-2800 (which is smaller in diameter than the R-2600 by the way) and swapping out the three-blade propeller with a four-blade propeller.
