I am surprised that the 'weight deniers' haven't jumped in to disdainfully suggest you simply grow a pair, eat more red meat and go to the gym. 😂
Weight is a big issue for me, as it is for many of us. A wide padded strap makes some difference but, as has been said, at the end of it all a heavy bass is a heavy bass. I recently bought a Yamaha SB-35 - a quality, rare bass which has zero re-sale value. Mainly because nobody has heard of them. Very much a heart over head purchase as I had one before and think they are brilliant. Anyway, it weighed 4.1kg - not massively heavy but a bit too much for me to comfortably wear for any length of time. I handed it over to my usual tech guy who (gasps from the back) routed out a cavity beneath the pickguard - reducing the weight by 400g, which was around 10% and has made a difference to how it feels on the strap. I believe his next move would have been using a biscuit router to delve even further into the body from the same outline but that hasn't proved necessary. Lightweight tuners can also usually save 200-300g in overall weight. There are lightweight bridges available. It all starts to add up. Or subtract down, if you prefer.
I had a '79 Fender Musicmaster for a while and found both a Squier Vista Series Musicmaster and VM Mustang were more to my liking. But that's me. Bottom line - it is your bass and you know how much it makes you happy - if you really like it and are not bothered by taking a hit on the resale value - which to be fair is the bottom end of the old Fender market anyway - then it is worth investigating. You won't be destroying a priceless artifact.
