Multiple projects within one db, IIS site, HF Dasboard

Basically, we have many projects, with recurrent jobs each. But create for each HF server instance (DB, ASP.NET web app, Dashboard) a bit too expensive. Of course, we can group them logically into few HF instances. But, is there a way to have one instance and, add there jobs as some kind of “containers”? So desired result would be: one solution for server, and few independent (kind of) for jobs.
