Yes, it is. Currently I think that the Chancellor/Marshall is somewhat (maybe 0.5 pawn units) weaker than the Queen. The Fers move adds about 1.5 pawn units of strength, plus another 0.5 pawn units for curing the specific weakness of the Chancellor/Marshall, leaving the Archchanchellor at about 1.5 pawns stronger than the Queen. This difference should be noticeable during the game, but it is probably not enough to decide the pawnless endgame K+Archchancellor vs. K+Q in favour to the Archchancellor.
Note that this comparison is made for the 8x8 board. On larger boards the Queen gains strength compared to the Archchancellor because all her moves are long-range, but most of his moves are short-range.
The specific weakness of the Chancellor/Marshall is that the King can directly attack it. Thus adding a move-only Fers to it does not cure this weakness. But adding it may equalise the Chancellor with the Queen (on 8x8, of course).
