So I convinced myself that I was being dumb when I considered replacing Alfhildr.  I think part of it was me thinking that making Pink into a space viking was kind of goofy and I should make a more serious character.

...I almost had to slap myself when I remembered that this is _Super Sentai_, which practically _runs_ on goofiness.  Making a "serious" character (unless the whole joke is that they're the serious one) would be so contrary to the spirit of the franchise as to defeat the whole point.  So yeah, I'm considering just reusing her.
