Although not strictly pointed out by Ishibumi, it's pretty safe to believe that it is. Both Ddraig's name (which is Welsh for dragon) and his 'nickname' "Welsh Dragon" kind of make it obvious. However, I like the idea about their links with the Gundam series. That may have served as a secondary source, or at least influenced Ishibumi's decision.
