Welcome. You could TRY the 0.8 coil if you must. IDK that mod and if airflow is adjustable and/'or wattage. Sorry, I suck at pods. There is on magic "resistance" you have to vape at, I have used 0.8 coils at pretty low wattage indeed and it has been just fine (vape quality wise) for me.
If this is some sort of 'auto" adjust thing or the coil just is the only change you could still TRY it.
I say that because as a dipper your nic tolerance is PROBABLY pretty high.
Also, it is very hard to DO YOURSELF in with nic overload although it's not a pleasant experience. Symptoms of nic overload include: hiccups, feeling flushed or prickly hot and cold, headache, nausea, throwing up (I did that with some really strong snus where the pouch burst open and flooded me all at once and I wound up puking the in the bathtub. But I was none the worse for wear after say 10 minutes really) and symptoms of that ilk.
So, if you try it, go slow and be cautious and if you start getting nic overload symptoms STOP.; You may want to have a bucket handy I considered myself lucky to make it to the BATHTUP.;
The only nic overload death *I* have heard of was some dude deliberately drinking it to off himself, and for all I know it's an urban legend but like, well, I think you could TRY.;
I have no idea fi that one coil will fit in the other coil, sorry.
Yes there are probably better pods out there but if yours is not currently behaving in a disreputable manner you could probably TRY it since it is what you have NOW.
Your other option is to dilute it, I would probably use a 50/50 blend of PG/VG all very easily obtained. Drop it down to 35 and try the 0.8 coil. Etc.
