You already have two conflicting thoughts above me. And this happens, only you can decide what you should do yourself.
RTK is useful to get over the scare of those intimidating characters. For me personally, I got burned out on RTK after restarting it a couple times. But I got maybe half way through but I dread those Kanji no longer. If you can finish it, it can be very useful. If you can't, you can at least get over the fear of Kanji with it. There are several subsets of RTK that allow you to cut the amount of time you need to spend with it like RTK Lite or Lazy Kanji Mod. Who knows, those might be more suited to your needs.
As for Core, It covers a great deal of important vocab you will need to communicate. And it's very useful. I personally am using using Subs2SRS in conjunction with Core. Core gives me a good base and Subs2SRS with my favorite anime keeps things interesting for me.
As for doing both Core and RTK at the same time, there isn't going to be a lot of overlap. RTK is in a wacky order, but it makes sense for itself. Core kinda builds upon itself, and I tends to start with more frequent characters first. But just because you meet a Kanji in RTK first doesn't mean it's going to be bad when you see it in Core or vise versa. I do not see any faults in stopping one for the other, but if you have the time, why not learn some of the language now? You could also try something more aural like Assimil or Pimsleur to learn some basic vocab while you RTK instead.
I personally find one of the big faults of RTK to be all the confusing synonyms. Second issue is you learn absolutely no real Japanese from it. It's not hard to make a simple mod to expose yourself passively to some real Japanese. I personally like this mod:
japaneselevelup.com/how-to-use-anki-to-master-japanese-part-1-kanji/
It basically suggests you add a Japanese word that uses the kanji to the front of the RTK cards. It's not needed to answer the card, but it's extra exposure to real Japanese and it really helps for those crazy English synonyms.
Anyway, my two yen. In the end, it's all up to you.
