Please don't Necro old threads, especially when your "fix" is pretty much the clunkiest way to do things.

To my knowledge you're describing something like a savestate system, in which case the "state" would still need to be saved and loaded back which would still take time, and depending on how the constituent mods were designed the state might need to be rebuilt entirely at any time for any number of reasons. There is not some magic fix for this when any poorly made mod could invalidate the whole thing at any time therefore negating any benefit of the system.

The filenames of one or more of your mods suggests you got them from a repost site. Please read up on the StopModReposts project (link in my signature) for info on why this is a bad thing.

I'm not sure MultiMC has support for Forge's new install system. Forge is designed to work with the new launcher and will not provide support for the old one.

Hastebin I think you have to copy/paste. I prefer GitHub's Gist service over the rest because it's free and has the highest capacity by far.

Try using the version of Forge that Pixelmon is designed to work with, this version is identified on their website.

One of your mods is broken and poorly written, please provide debug.log (more info in my signature below) for a more detailed answer.

Looks like an issue between Thermal Dynamics and Mekanism with a Thermal Duct pushing into a Mekanism Factory of some type. Debug.log might have more info.

Try a newer version of Forge with updated mods. Merged your threads. Please read the Logs section of my signature below and provide the appropriate log in the appropriate manner.

1.7.10 is no longer supported on this forum due to its age. Please update to a modern version of Minecraft to receive support.

What launcher are you using? Please provide a screenshot.

I don't know what mods you're using, but modern Minecraft will barely run on 512M and almost any mod will make that impossible.

Also I would not recommend using Openj9 with Forge

I honestly can't remember if they do their own separate game install or not. Please read the Logs section of my signature below and provide the appropriate log in the appropriate manner.

Update JEI

Where did you get Forge from? Please provide a URL.

Installing a new version of Forge doesn't require uninstallation of the old one, just install the new version and edit your launcher profile/installation to use the new version instead of the old. For the most part mods SHOULD work with newer versions.
