The Revell kit is very old and basic, it can be enhanced with parts from MDC and modelling skills (re scribing), if by Paragon parts you mean the bubble canopy conversion you are probably better off buying the MDC resin kit. I've built both as I wanted a car door and a bubble top in my collection.
Both are challenging in different ways but they are worth building, I would still be prepared to buy the rumoured SH kit though.
My Revell kit was built in the 90's and rebuilt in the early noughties and I have a soft spot for it.
Here is the build thread for the MDC Typhoon it also contains some photos of my old Revell effort, I cannot find the LSP build thread, there is one somewhere so it's the Britmodeller version..
And here is the finished article, https://www.britmodeller.com/forums/index.php?/topic/234972035-mdc-hawker-typhoon-finished-at-last/
