G... You might find just your Springfield sporter 35 Whelen as you describe. But I'll bet you'd probably be better off playing the whole field of Springfield sporter general conversions, picking one that best matches all your other requirements and just have it rebored with net of brand new barrel in effect. Odds better and considerably more likely to end up with what you want!
Just my take!
Happy New Year!
