I just noticed that you started with the Cosmos and the Curare. I had a look ant some of the relevant parts, the Cosmos is has much more complex parts. The Curare has only few of them. - like NBD1 NBD2. NBU is a part where it would make sense to mill it to the final shape. But the question for me is: should it be a ''pure'' Kato kit or a are modifications allowed.
I remember I still have my old OS 40VF - I used it with an OPS tuning pipe - it was really loud, but the power was exceptional - its rather something for the Aurora 45
My feeling is that there is no issue with allowing modifications. However, MK kits are so well conceived, designed and produced that I personally see no need for them. My preference would be to not have those directly involved with the project do any more work than necessary. If there is something that you feel could or maybe should be improved on, then perhaps this could be addressed after the prototypes are built.
There might be some interest in attempting something similar in terms of kit conservation for the larger 40 and 60 size kits. I don't personally plan to entertain that idea for this project. The effort is quite time consuming and requires considerable amounts of work from all those involved and so I'd rather keep this thread focused on the 20 size kits hoping to move on to other designs once the goal with the Cosmos and Curare has been achieved.
Your 40VF sounds like a great match for the MK Arrow 40 as well. I hope to build my kit sometime next year. YS 45 FR and Hatori pipe powered.
