The problem with current Hathor is the texture and overall superstructure which appears to have plenty of nonsensical weakpoints that neither fit Freelancer style dieselpunk aestethic or Order/Liberty highlights. Idea for the cargohold would be to fill out current Hathor's belly, removing quite nonsensically placed engine intake while also making sure the wings would connect. The odd exposed Rheinland-style reactors may be a better fit for a non-combatant Zoner gunboat design. Personally I have nothing against the current gigantic flying wing shape but I will allow myself to be surprised under condition that it remains a competitive heavy gunboat statistic-wise.
Jinx proposed version which is NOT old Hathor but a shortly lived 4.86 replacement that strayed further from god moved even further away from fitting in-line with rest of The Order ships. The amazing black Hathor at least has a dark texture and bricks fit Order slightly better than metal tentacles - I think we can all agree as to why.
EDIT: I should add, the role of Hathor in Order shipline. From INRP standpoint, our reconaissance order cruisers (ORC) are valuable and considered fully fledged capital ships in their own right and therefore they are to be escorted as opposed to being an escort. Order lacks any kind of destroyer type ship (unless you would rather stretch already thin line with Zoners by spamming their Q-ship), compensating with a heavy Hathor for the role. Think of it INRP-wise as versatile VERY LIGHT DESTROYER (still within gunboat classification by size and guns, do not mistake with Orca) that is both a heavy assault ship as a natural step up from fighter ships and simmultaneously an escort destroyer for ships larger than itself.
