Passive TV splitter inside back box?

OK, this should be easy for someone.
Firstly, let's assume a strong enough signal to take passive TV splitter at the bottom end of the cable from conventional aerial.

Is it reasonable then, to take an existing single TV outlet in a standard inset wall metal back box with front TV socket plate, and fit a passive splitter inside the box, so that a second cable could be passed out the back through the wall?

I'd be concerned bout mangling the co-ax because space would be very tight. I'd be happy to re-fit a deeper 50mm back box if that was required, but I suspect that may still be too tight.

Maybe there is a product which does this? (I'd envisage a TV plate with one coax in, one socket out to the front, one socket/co-ax out to the rear). If there is one, I've not come across it.

Such in and out plates are made but not often a good idea. Another option, hardly ideal, but an f type splitter could be put in a stud wall. If the wall is solid I would look at doing it another way, jamming loads of connections in the back of the box is just going to end with damaged cables and signal problems. A possible way is to fit a deep dual box one side to house connections the other the tv point, use an f splitter with all 3 the connections on one side. Removing the central divider from the box will allow plenty of space for wide cable bends.

Thanks, good plan. I like the idea of using a dual box to make the space and avoid crushing the co-ax. Could work well
