[Feature Request]: merge models on the fly

[mhnoni]

Is there an existing issue for this?

• I have searched the existing issues and checked the recent builds/commits

What would your feature do ?

Instead of having 100 models in our hdd, we can have only the base models and we will be able to do merge on the fly and load it immediately after the merge process to get any kind of models without saving it to permanently on the hdd, or on the ram. since ssd is fast, this will help us a lot.
now we can pick virtual model from the menu which is just a simple txt file that contain the recipe of the models and combination value.

Proposed workflow

1. Go to Stable Diffusion checkpoint
2. pick the txt model which is just a txt file that will merge the source model and load it.
3. generate images now with the current merged model.
