If you've got a genuine multirole (as in "perfectly capable at PvE combat"), then high-waking is certainly possible in that situation. It's boring but unless you have an extremely specific need to be in that system it gets the job done.
If you
don't have a ship which can evade and/or tank 20-30 seconds of fire and then high-wake, then your problem is not stacked HRPs and SRPs.
Here's my Powerplay multirole build:
https://s.orbis.zone/qMzZ (some of the engineering might be slightly off, but close enough)
- not a single hull reinforcement or module reinforcement; in return, the internals are full of things which allow it to do every Powerplay action in the game except mining
- it does have a few shield boosters but it's still only a biweave Krait with minimal hull
- if you're flying a slow and poorly defended ship [1] none of that matters because you won't be affecting even my lightweight defences, and I still have exactly the same
firepower as a PvP murderboat because bringing that doesn't compromise my non-combat build in the slightest.
[1] In a Powerplay context where it's actually worth me opening fire, let's assume. That's by the far the most unlikely bit of this hypothetical.
