It is possible, but usually you want to have DRS enabled, still do some vMotions etc. these things can quickly add up quite a bit.
Have a look here how DRS alone can get vCenter under enormous pressure: http://fbuechsel.eu/2014/06/15/used-features-impacting-vcenter-server-minimum-requirements/
And now imagine you want to add all those create, poweron and delete tasks on top of it. Furthermore what happens if something goes wrong with the workload infrastructure, your management system will reside on that very same infrastructure. It might not sound much right now, but noticing that you can't do certain tasks in the amount of time you would need to could really hurt your SLAs.
