My take on a Draken upgrade. Mitsubishi F-1 wings. BAe Hawk horizontal stabilizers. And other goodies not yet finalized.
If I may be so bold as to suggest, possibly extend the nose a bit and reshape it to take a larger radome, form something like a Phantom or even a Viggen. The Draken suffered from insufficient sensor capability at the end of it's life and a good update would be a larger, better radar and the ability to fire things like the AIM-120 or Meteor.
Change the exhaust to something like the petalled exhaust of the F-100/F-110 better performance, more range.
Just spitballin' here...

Good spit balls.
Saab already selected the Carlsberg Group OM79 engine. The Carlsberg beer company of Denmark (J35 users (the Airforce, not the beer company)) was looking to diversify it's business. It asked it franchises to keep an eye open for any opportunities. .
The Swedish office found one in the Draken Plus program. The Swedish Carlsberg team using it's resources from it's beer division learned from beer loving Svenska flygvapnet pilots about the Draken Plus project and they were looking for a new engine. They took this information back to Copenhagen where it was discovered some parts of the beer brewing process could be used to enhance engine performance.
After some trial and error, Carlsberg was able to increase J79 performance by 10% with a only a 5% change in design. They proposed the design to Saab who liked it. Carlsberg got the contract and we now have a licensed built PW J79 engine, OM79. OM being ölmotor or beer engine.
Okay. I had a left over J79 exhaust from a F-4 and I glued it on. Can't back-out now.

The nose is about 2 feet scale / 9mm across so I need to find a radome which is similar in dimension. Any ideas?
