I know this does not have a theme but I think that is okay. Ones I should add, ones I should remove, ones that are not compatible.... I know that there is a lot of mods but a decent computer can handle them. I also want to know whether or not you like this or if you would play this.
It's a good selection but you may have trouble with lag from several of the mods you've listed. Any mod that adds entities to the game can cause large amounts of lag and some of the mods listed, Advent of Ascension, Mo' Creatures, and Minecraft Comes Alive, are among the worst offenders. Also mods such as Botania can cause frame rate issues due to the particle effect on flowers, I believe this can be disabled in the config. You should also know that Fossils and Archeology and Archimedes' Ships can be fairly buggy to use, use caution with Ars Magica 2 as it's known to be unstable and hasn't seen an update to fix this. Just keep everything I've said in mind just in case the worst happens, otherwise enjoy and good luck.
