Seriously? I mean, everyone's goals are their own thing, but this just sounds so... defeatist. Like, you'll turn in your gym membership and quit lifting at 27yrs old because you can deadlift 315?
I'd rather not assume jack squat (pun intended). What does your weekly training look like - the days, exercises, sets, and reps.
Also, what seven basic movements are you referring to?
Like Ecchastang said, soreness has very little to do with programming in the way you're talking about it. I agree that certain exercises and techniques seem to bring more DOMS, but also nutrition plays a big part in it. Skip a workout shake and/or go low protein the day after a hard training session and see how perky you feel.
And anyhow, it's not just singles that build strength. Total volume is much, much more important. It could be argued that you'd see better results from something like 3x3 instead of just singles.
The goal is reasonable, without a doubt. It looks like the raw squat world record for 165-pounders is over 600, raw deadlift record is over 700. So, yes, a guy your size can squat 405 with hard work and a well-designed approach. The plan you're thinking about using (even though you've been vague with the actual details) and the multiple self-imposed limits you've set up are not reasonable.
