After looking at a few other mods to speed up the respawn times, I found myself very disappointed that there wasn't one that was both fast enough to have a noticeable difference, but also slow enough to be realistically possible. Therefore, I went to the extent of doing it, myself. Very easy to do on your own with Creation Kit, but for those that don't know how, don't have it, or simply don't want to bother, here you go.

The respawn times I set were 3 days for all cells and 14 days (two weeks) for cleared cells.

My reasoning for choosing these times was because I don't think it would necessarily take ten days for a man (or woman) to restock his (or her) market stall, or game in Falkreath Hold to take ten days of you being nowhere in sight to show up after you went on a hunt - despite there being other hunters in the area, anyway. But I also took into account that it wouldn't make sense for places like Dragonsreach to be fully restocked within a single day of being wiped clean. I figured three days was a much more realistic medium. As for dungeons taking two weeks... One month is reasonable, but it's a heck of a time to wait - especially if you've altered your timescale to something like mine (1 minute real time = 10 minutes game time) AND have waiting and fast travels disabled. However, it's not realistic for a place that you wiped all life out of to be back to life after only one to six days. I figured the place needed at LEAST two weeks to have a good chance for that to happen.

I wouldn't normally bother doing this, but since I seem to be more into modding now, I may as well point out my other mods.

Coldhaven Ingredients Adjusted
This mod (requires Brehanin's Coldhaven) makes Coldhaven's ingredients more worthwhile and even special - allowing for the creation of potions such as Waterwalking and Fortify Alchemy. (Don't worry; it's not without the appropriate difficulty to balance out the brokenness.)

Crystalline's Black Soul Gem Crafting
This mod allows you to craft black soul gems from the fragments you find. There are a few options to this one. Plus, there's even a mod nestled in
that page that renames the fragments to tell them apart easier - completely standalone. Use that with other fragment-to-gem mods, if you want.
