I would definitely upgrade to film caps wherever they're in series with the drivers, and go for new electrolytics in the shunt positions.
Yeah that 150uF in series with the mid is a big value, and a Solen or similar will be the size of a small soup can and probably set you back 40-50 bucks each, but you could also parallel up 15 of these 10uF Tyee caps (see link). You'd need 30 of 'em for both speakers, but at 60 cents each, that's maybe the best 18 bucks you'll ever spend. I've used 'em in several projects and like 'em just fine.
I'm by no means an exotic capacitor cultist, but I can sure hear the superiority of ANY film over ANY electrolytic in series with a driver, even though I can't really hear much difference between regular and fancy film types. With the midrange driver covering the most sensitive range of human hearing, you want to treat it nice in the crossover
