How to map normal mode to modifier key on keyboard in vim (say Alt)?

Question

I want to make my workflow in vim a little bit faster for me, by working all the time in insert mode, with executing normal mode commands(keybindings), when I hold some modifier key, say alt.

So, for example, I'm currently in insert mode and I want to call undo command, instead of typing <Esc> <u> <i> , I want to type <Alt>+<u> , and return to insert mode immediately.

I know, you can map all your mappings via imap/inoremap explicitly for every insert mode mapping, but I want to map ALL the normal mode mappings, even those used in my plugins, and this is too much work. Also, I know there's <Ctrl>+<o> command to execute only one command in normal mode with returning to starting mode right after, but I want to be able to execute any number of commands in insert mode, not just one, and not to execute any, if I just hold <Alt> key (or any modifier I set for this behavior) and then release, not switching to normal mode.

PS if someone heard about vim-clutch , I want to make the same, not buying extra one pedal for release event, having only one pedal.

thx.
