I see what you're saying; it's not a bad fit. Problem is, that's in the forward cowling and they don't open that for routine work. I can't find a picture anywhere. Got lots of pictures with the side cowl doors up.
ETA: Here's a fairly poor image from a training manual. The trainee drew in the LEAP modifications. I don't know if LEAP changed the mounts, never saw a mention of it. Anyway, you can see the structure is a possible fit.
