I've done both Whitney and Charleston, and can say Charleston is definitely easier but, nonetheless, still to be respected. But although the hike will tire you, you have the advantage of being in the best of shape right now since you recently did Whitney. The time since doing it and arriving at Charleston will be enough to ensure no disadvantage from doing Whitney -- i.e., any physical soreness from Whitney should have dissipated.
You are correct in that the South Loop Trail is still closed. I had done my Charleston hike using that first and then returning on the North Loop Trail. Either that route, or vice versa, is preferable because variety is the spice of life. On the other hand, the disadvantage of that is a 1 1/4 mile walk to get back to the other trailhead where your car is parked.
So you'll avoid that end of hike effort. Also, bear in mind (you may already know) that the "North Loop Trail" is, technically, a route 2 miles longer than the shortest way to climb Mt. Charleston using that northern route. The trailhead for the North Loop Trail is at a completely different location than what you want -- you want the "Trail Canyon Trail" trailhead. That's the trailhead 1 1/4 miles away from the South Loop trailhead. (The Trail Canyon Trail goes 2 miles and HOOKS UP with the "North Loop Trail". You hang a left there.)
The South Loop Trail is NOT shorter (perhaps you WERE thinking of the longer distance involved for the complete North Loop Trail) given the above. Its basically the same distance (although, technically, the South Loop Trail is actually slightly longer). Doing the hike either as a loop using both trails OR only one of them is about 18 miles round trip, compared to Whitney's 22.
Also, not sure where you got your elevation facts. The summit is at 11,900 plus (15 or 18) feet, NOT 11,500. The South Loop Trailhead is at roughly 7,700 feet, likewise the Trail Canyon trailhead. Either way you've got about 4,200 feet in elevation gain, not the 3,300 using the elevation figures you had (compared to Whitney's 6,100 feet of elevation gain).
Also again, not sure where you got the idea of the northern approach being "more up and down and up and down instead of a steady climb" -- not that way at all. Sure, a little bit of it, just like any climb, but basically it's a steady climb. (Or, in my case, it was a steady descent.)
The one important thing about using the northern approach up is that the last mile is ESPECIALLY steep, with a bunch of switchbacks at the base of the face.
I did Whitney in 8 hours and 45 minutes up and 4 hours and 29 minutes down. Charleston was about 6 hours up and 3 hours and 45 minutes down.
Hope the info dump I've given you helps you in making a correct decision for you vis a vis climbing Charleston or not!
