No. If they make him shardable, all other players with Pd prior to this should get a 3 headed molt with 5/5 revite and free 5/5 zerk/revitalize on their Pds.
I share your frustration, as i too lack PD but if everyone could access him through shards, it would make the game less exciting when you finally get one by chance out of a roll.
i suppose the next thing you're gonna want is for all rare legendary heroes to be bought with shard
Deal with the way it is or go start your own gaming franchise and do it better
