More interesting, cutehunkie?
I for one find the question itself very "interesting." After all, isn't the sexwork professional in charge of "spicing things up?" On the other hand, if she is working from a well-honed script, then maybe she won't want to go with some of the role play, toys/lingerie or anything else you want to cook up. As far as lingerie, doesn't she have some of that already? Of course you can request anything that tickles your fancy - no harm in asking.
In general, however, women - providers or civvies, doesn't matter - enjoy a man who listens to them....although it doesn't sound like you were finding the chit-chat itself sexually arousing. I'll say this though, and that is that if you are planning to become her "regular," chances are that she will reveal a lot more of something - whether it's her off-the-clock personality, or just details she wants you to know about her private life is anyone's guess. But the fact is that most women need some sort of non-sexual "connection" to get more genuinely and naturally sexual. Yes, it's a paradox, but that's how women work. The more non-sexual attention you pay them, the greater the chances that they will abandon themselves to the ultimate in Eros and let themselves be taken over by multiple orgasms, wild expressions of lust, etc., much for your benefit as well as theirs.
Sure, if you want her to put on a different or better performance, then pull out all the stops - toys, lingerie, role play, kink, BDSM, sex in unusual places, sex in "public," phone sex, bringing in another woman, watching her with another man, playing pickup games in public, etc. - the possibilities are endless. It just depends on what you want from the encounter..more of a PSE or GFE?
Just know that you might have to work a little harder to prevent the "regular" from really becoming so,
