It sounds like you want to create a system wide federation. Several
public state higher ed systems have already done this (eg see
UCTRUST, the Texas system, the NC system, etc). Sometimes the
statewide federation also includes state and local government;
sometimes the plans also include bringing in K12 at some point.
You'd want your federation to set "common policy" for the members.
This might be a higher bar than is currently set by InCommon. It
might be useful, tho, to look at the recently promulgated InCommon
"Silver" standards, which match the federal e-authn Level 2 (and will
grant access to applications such as NIH grants mgmt, and
(eventually) Dept of Education FERPA).
As a starting point, each campus would likely have some people at
"bronze" level, and a smaller set at Silver (people who need to
access applications in ways that engender a higher level of risk).
