Default Engine movement?

One drawback of moving my engine mounting forward by 35mm is that I now have a point where there is only a small clearance between the sump and the chassis.

(This photo was taken looking down from above the chassis just behind the nearside engine mount)

The gap is about 6mm and I'm wondering how much the engine and gearbox will move forward under hard braking.
I know this is a 'how long is a piece of string' question and it depends on the weight of the engine plus the stiffness of the rubber in engine mounts and the gearbox mounts, but just wondering what the views of forum members based on their combined experience.

I think it would be possible to cut off the corner of the sump and have a flat plate welded over the hole but don't want to go to that expense if it's not necessary. Also, any advice on where you would get an alloy oil sump welded would be appreciated.
