Low Side Switch

So with my rewire I purchased an Eaton VCM and ran into a problem.. Normally my ignition and all the things it powers are high side switched. The Eaton is set up for a low side switch. Anyone see a problem flipping my ignition into essentially a grounding bar therefore a low side switch? The relays would then power everything else in their usual way so I can't find a flaw in this plan but would like other opinions.
