While that's something you could do, the chances of there being random falling debris without someone having destroyed a bunch of stuff within seconds of your arrival is so incredibly unlikely that to cause it using your luck semblance would leave you almost completely drained. It'd be a lot easier to use your luck semblance to 'Just happen' to land in a perfect spot, or something along those lines. I mean, if you want to go ahead with the original idea sure, but you'd probably die to the first Beowulf you encountered.
