You need to setup an addon profile (there are 2 addons able to provide addon profiles and you use them as I can see it by your comments) which will not use MM and all the other addons you do not want to test.
Then simply reload this addon profile without MM and the reload will only take seconds
I don't know any other way without having to change several addons. And beside this I don't think it would work as all variables will be reset at /reloadui and will always prevent/always allow to laod the settings then.
