A D-11, D-12 would be more probable choices, they saw more realistic production numbers and some, actual combat action.  As has been stated, I think less than a handful of D-13s were completed, and I don't think any of them saw combat even though at least two or three made it out to operational units before the surrender.  Since we have the Ta-152 H-1 which has a 30mm engine cannon and two 20mms in the wingroots, thats kind of an acceptable alterantive.  Would be cool if one day we had either the D-13 or a 152 C though - but I'd hope to see it after a couple more A-series 190s and at least another D-series, otherwise it'd crit my gufaw-meter.
