I havn´t seen anyone doing this but thought that it could be done, kitbashing Gripping Beast excelent plastic Hirdmen with Conquest Games Norman infantry.
The plan is (besides giving me some more cheep miniatures) to create something that could be used to represent Norsmen Gestir troops.
Statvise they will be someting in between Hirdmen and Bondi but more about that when they are painted.
And I found a use for all those extra arms from Wargames Factory... to help me in my kitbashing.
I think they turned out rather nice but things to have in mind is that Gripping beasts necks are on the torsos and Conquests are on their head.
I covered the joints with some liquid greenstuff after I used the shoulder parts from the left over arms as the neck.
Hope it can inspire you to test something diffrent.
