No.
There is some context behind it.
"Group buys" where you team up with a lot of other people to crowdfund a miner purchase, used to be so popular for buying miners that Bitcointalk even created a subboard for it.
The idea is similar to yours in that they own a percentage share of the profits the miner makes in solo or one of the PPS modes.
However, as miner prices skyrocketed and people lost interest in the idea, others became priced out of the endeavor.
