As someone that also uses both WaniKani and Bunpro, I can offer my perspective. WaniKani is based on kanji complexity and builds vocab out based on that; thus, it doesn’t necessarily follow the JLPT progression. Personally, what I do to avoid burnout, is 5 lessons on WaniKani a day along with 1 grammar and 5 vocab a day on Bunpro. It is not a fast progression, but it works for me, YMMV. Make sure you sync WaniKani progress to Bunpro in your Bunpro settings. The beauty of using both Bunpro and WaniKani together is that as you make progress on your kanji and radicals knowledge, it will make learning vocab in Bunpro so much easier. Likewise, when you encounter vocab from Bunpro in WaniKani, half the battle is done and you gain the richer, underlying aspects of the vocab. Often times I will encounter a new vocab in Bunpro, and it will click much faster based on radicals/kanji knowledge. I bounce back and forth between the applications and deep dive into specific kanji and allow that interest to naturally deepen the knowledge/branching out from the root.
With regards to communication, that is sometimes the easier the part, as practice makes perfect. However, it is easy to get stuck in a rut where your language doesn’t improve and remains static to the vocab and grammar constructs that come naturally. This is where Bunpro and WaniKani will continue to push your envelope. Practice with your aunt as much as possible. You are very lucky to have an option like that.
Best of luck in your language journey!
