simple designs are usually superior to complex ones. - you don t become tired too quickly of the more simple ones. - but its harder to make a simple, yet fitting design. - one tends to add stuff here and there. mind that depends on the faction.
i think that for example spikes and stuff fit to corsair designs - but BHG ships are rather plain. - they have very small engines, a large but not too sophisticated or decorated cockpit and 2 very basic fins. - thats it.
when you compare them to the liberty or the kusari ships, the BHG ones are allmost only basic concepts. - there is no ornament on them, no wing that doesn t need to be there etc.
i think the star wars corellian corvette models do actually fit the roll of the BHG, they do come with too much stereotypes - but if you manage to make the ship really the way that drawing shows, - it would be one of the best fitting concepts possible for the BHG, i think.
just like i said - be careful with the turret hardpoints. - they can ruin an otherwise perfect model. ( like the BHG gunship )
and - like other extreme replacements - the shape makes the stats. - this ship looks lighter and much more agile than the current ones. - so a simple replace and copy / paste of stats wouldn t be logical. - however, i think people are not too happy about the BHG trend to get superior agile and small ships ( bhg bomber / bhg gs )
