AJ10-138 Adv. Short nozzle, is maybe a bit too small.

The Titan IIIA had introduced with it it's third stage, called the "Transtage". It used two of the AJ10-138's to push into orbit and beyond.
However, when making a Transtage upper stage, it is very noticeable how small the engines just are compared to the stage, the nozzle is just too short. This wasn't an issue back when Short and Long nozzles weren't separated, so here's a solution:

AJ10-138 gets a long nozzle model, but AJ10-118F remains with the same, very short nozzle model.
OR
Both Long and Short unlock in the same node, however AJ10-138 is now in the Long variant (it's later upgrades wouldn't be unlocked until the 80's tech nodes) and Short only has 2 upgrades (That being the AJ10-118F and 133-LH)

Here's a comparison between my Transtage and the real Transtage:

The short model was added because the long nozzle model does not fit within the 3 meter diameter of transtage

The short model was added because the long nozzle model does not fit within the 3 meter diameter of transtage

If I recall, yes, it does fit in 3m of diameter, however it'd be very tight. I think my idea right now is to bend the shape of the nozzle by using the same magic that was used on the RD-0105's recent config. Is it possible?
