Op1 with pocket operators

I own an op1 which I love. I generally record it with a zoom h4n. Considering that sometimes I would like to have more tracks available do you think it might be a good idea to get a couple of operators (for example the drum and the bass ones) so to have all the 4 tracks of the op1 free for pads and lead?
Is anybody using the op1 with pocket operators? I would appreciate if you could share your experience.

why do u feel u need more tracks?
u know u can overdub, bounce and all that fun stuff on the op1s tape tracks.

I know that…however sometimes I would need some more tracks for the arrangements…this is why I would think to add one or two pocket operators so to keep the bass and drums free
