Kerbal Hiring Improvments?

[DStaal]

As I'm waiting for KSI Placement Services to be updated, I'm getting a bit Kerbal-starved in my new playthrough - despite hiring any non-stupid Kerbals I see.  But I also tend to feel that mod is a bit overpowered, especially when playing in science mode.  (Where funds don't matter.)  So I wanted to float the idea of a slightly less complex hiring improvement mod.  Here is what I'd like to see:

• The number of Kerbals available to hire is kept stable - You hire one, and another is immediately placed in the available pool.
• Firing a Kerbal removes them from the game entirely.  They don't go back so you can re-hire them.
• Pool refreshes don't get changed.  (So if you leave the pool alone for a couple of days, you get a new collection of Kerbals available, just like in stock.)

To me this would be a bit more realistic (NASA gets something like 10,000 applicants for each available astronaut slot, so the 'available to hire' pool is what you'd see after HR gets through screening them), it's still balanced in that costs don't change and in the cost-free modes you can't just specify intelligent fearless badasses, but it means that I'm not going 'oh, I can't launch that trip to Mun because I don't have any scientists or engineers available'.  (Even with my orbital stations at one-quarter staffing.)  On the other hand, I do have to think about whether I want to hire that low-courage relatively high stupidity engineer for my EL build station, or if I want to wait and see if someone better comes along.

Anyone have any interest?  At some point I'd like to try my hand at modding, but it'll have to be after I can afford to upgrade my computer to something made this decade, so it'll be a while.
