Now maybe this is a stupid question, but how would I know if my current front sight is tall enough?

There's really no good way to make absolutely sure without testing it at the range. There are calculations available for determining sight heights but I've never seen one that applies to aperture sights.
If you go with XS sights, you might want to just install the front sight that ships with the ghost ring. If you have trouble with the height, they will work with you on obtaining the correct one. Plus, the XS front sight is very visible in most reasonable light conditions so it is a pretty good option anyway.
If you buy a Skinner aperture sight, try it with your current sight. If the front height doesn't work, contact Skinner and ask them to make you a new front sight. I'm sure they will help you determine the correct height based on the results you get with your current front sight. Or you can ask them for one that you KNOW will be high enough and then file it down a bit if necessary.
When all is said and done, there is no way to be sure you have the ideal sight setup without putting rounds downrange.

buy the Williams Fool Proof and the matching fire eye front sight as a set.
Midway has them on sale every so often and you basically get the fire eye for free.

Most times, IME, there will be more than enough elevation adjustment on a conventional Williams or Lyman receiver sight to work with the stock front on a Marlin LA. This, however, doesn't hold true with many other rifles as the difference in height between the open iron rear and the new peep is much more pronounced.
When I put a Williams Guide receiver sight on one of my 10/22s I had to replace the front with a 0.538" one to get it zeroed on the paper at 25 yds and have adequate adjustment room left on both ends of the scale.
Brownell's catalog has a chart which lists precalculated figures for some common rifles with the necessary stock base figures and recommended changes for use with the replacement models they make for them.
There used to be a chart showing a formula for how and where to take measurements and calculating front height changes from those data when switching to a receiver sight in there too, but I've long since tossed all of my older catalogs and can't find it. It was sorta tricky, IIRC, as it required precise measurements from the bore centerline, sight radius and some trig. I'm sure that somebody out there has a gunsmithing text that has something of the sort in it, but I don't.
