I understand where you are coming from, I’ve cut up the back of my leg pretty badly twice and still have a slight scar years later.
I think the pins are removable on quite a lot of pedals, even the Nimbus ones as far as I remember, so you could remove some and only leave a few, which may reduce the risk of one of them getting you. That said I seem to remember a line of parallel cuts up the back of my leg one time like I had been clawed by a big cat – that would have been from a Nimbus pedal and the pins on those are pretty blunt compared to some others.
Some pedals have pins in the centre section as well as at their leading and trailing edges. It is difficult to know if those would “get” you more than the ones on the edges or not if you just left those in, I guess it depends on how you fall.
As others have mentioned you could always take a grinder to the pins and shorten them and round them off so you retain some grip.
I have Hope F20s on various unis and bikes. Even without the pins fitted I think you would get a good grip from the milled grooves on the platform. I would be reluctant to recommend them just to try though because they are pretty expensive (and if you fit the pins they are pretty aggressive (they come unfitted with the pedals)). You can hopefully see what I mean on this post:
