Limited space for MMU3 - will this work?

As you can see from the below - I have limited space. I print only as a hobbyist - nothing to sell etc, so all very casual. Once I have completed a print I put my filament spool (just use PLA) back into its airtight bag for storage until the next use. 

I'd like to tinker with multicolour so a considering a MMU3 - my issue is therefore obviously space. 

I'm thinking of installing a shelf on the wall above the printer. I will place the 5 spools on the shelf complete in air the tight cereal box setups so that i don't have to worry about sealing them up after every use and can just leave them in place permanently.

My plan was to then to print a bracket so that I can place the coil/buffer cassette thing under the shelf. Would this work - can the buffer be placed horizontally instead or vertical?

That way the filament would feed from the spool on the shelf, round to the buffer thats under the shelf, then directly down to the MMU3 thats underneath. The filament runs should be quite short, although leaving a curve each time of course so that filament can easily flow.

Would this work?
