"Why not modules instead" is a bit of a common question, so on a whim I threw together a concept for just that.
New Module: "Warp Speed Lowslot"
Requires Warp Drive Operation V
50 CPU
+35% Warp Speed
The most obvious issue with low slots on freighters is lack of a warp speed rig. Solve that with a warp speed low slot. At +35% you get a bit larger benefit than with three T1 warp speed rigs, though smaller than three T2 rigs, but at 50 CPU you'll be making some major choices to fit them. The high fitting cost also serves as a check against their casual use for subcaps, as they'd be a huge, huge deal for shield tanking subcaps. 50 CPU isn't necessarily a final number but I'm not sure about going lower either.
e: Has been pointed out to me that this module would instantly obsolete the new Angel bonuses. This is somewhat problematic, but for now I'm not going to worry about it.

Still no free lunch here; you're not getting better at everything at once, unless I messed up somewhere. For the most part it hews to the same overall principles as with rigs (tighten the gap between the different classes a bit) but the upsides are bigger (though the downsides are too) and you can hit a lot of interesting combos. It also doesn't demand a fortune to swap. Use of low slots is obviously an advantage for the armor tanking freighters. To offset that, shield freighters put a great deal of their EHP into shields while armor freighters continue to focus mainly on structure. This has the following effects:
- Fully tanked (DCII+2x Bulkheads), armor freighters have the most EHP, by ~10% or so.
- When "low penalty tanked" (DC plus either two PDS II for shields or two hardeners for armor), armor has the most EHP by about the same ~10% when considering blaster damage specifically.
- With two tank mods, they're about even.
- With one tank mod, shield freighters have slightly more EHP, and more still with no tank mods.
A few fit examples for illustration; this all assumes all skills at V and Tech II mods.

One warp speed low is 1.85 AU/s. Two is 2.41 AU/s. If the CPU allowed fitting three, that'd be 2.9 AU/s.
Going to sleep now, if people like the idea maybe I can whip through jump freighters to illustrate them as well.
