Although I am not familiar with this, I don't see any reason for not doing it.
If it happens in real it can be done in a model. You have the skills and the knowlegde, so go for it.
Don't forget, measure twice - one cut, test fit test fit and test fit.
The smaller scale of the engine it will not be noticable at all and also works in advantage for you, smaller size more space...
Keep us posted.
