By all means connect with Mica as everything built by Alembic can be customized. We reduced weight on my Medium scale Signature by going with a 3/4 size body, doing a fairly deep tummy carve out and other things. Now you need to keep in mind that some things you might want to do could impact the sound of your instrument (e.g., are you going to forego the typical dual Purpleheart stringers in the neck) but Mica can inform you about all of that. Other things to consider would be whether not avoiding a back laminate would bring the weight down, using plastic vs. wood vs. brass control covers, specifying a non brass block under the bridge, using ultra light rather than standard tuners, etc. I’ve always wondered whether a Series I or II specifically built to be used with a SF-2 and F1-X for tone shaping would allow one to keep the Series sound but reduce the weight of the electronics in the bodies of Series basses and if this would really make a significant weight difference.
