Not really a serious idea i just lowkey think it would be funny if there were bounce versions of the landmine/claymore.
Could be used for some creative traps such as launching a player into spikes, turrets or just straight up fall damage (in the context of servers with broken bones and bleeding enabled).
Can be an interesting option for mobility bounce wise as landmines arent on a timer or require a detonator.
In short i think a bounce landmine would expand mobility options explosive wise (and probably be used as a cheap way to get a free kill on someone that didnt see the bright orange landmine)
