Hall of fame bonuses?

[Taqwus]

That... would be a lot of additional units. Either that, or they'd need to rework mummification, e.g. cover the original non-transparent parts in some weird wrapping texture (argh, not easy, esp when you consider weapons etc) plus deltas to the stats/abilities.
And don't forget Gift of Reason. What would a mummified Vastness, Horror or Krakenlook like?
