There are a few problems that you will run into on something like that:
Landlord will require someone to be responsible for the entire lease. You will first have to find someone to take responsibility for the whole space and that person will still be required to pay the entire amount even if the others don`t pay him. Also the others will need to have confidence that when they pay him that he will pay the rent. If he does not pay and locks you out those that are renting from him will have no rights.
Now if there are a group of people that are all friends and trust each other it could work out well. You will want to make sure that the landlord is aware of this otherwise he could site you on the "no subleasing without Landlord approval" clause in the Lease.
My opinion on your best bet to make this happen is to look at older properties. Usually older properties tend to be willing to do different things. Newer properties usually aren`t willing to do anything other than the standards. You also might be able to find a small warehouse that you can handle on your own or just for two of you.
You also need to be aware of that if you are sharing space with other that you are holding merchandise, that people will accuse other of taking some of their merchandise when it goes missing. Someone else might have an employee that comes and gets their stock but is not the most trustworthy. Basically you need to have the trust in the others that you are sharing space with.
Also, don`t rule out office space. Sometimes you can find some small cheap ugly office space that will work just as well.
Sorry for rambling on, but having been in property management for over 10 years I have seen these things cause problems, but I have also seen them work out. Recently I even stopped two people from doing one as they didn`t know each other but were trying to get a better rent. Turns out this one went south so it was good that I stopped them from renting together.
