A conversation about basic technique from the Tonya Harding thread sparked my interest in present day skaters that are able to improve their basics. Kostner and Asada are two skaters that omitted their weaker jumps from programs in order to earn a maximum score under CoP. However, it seems that deductions from TES and low PCS generally tend to lead skaters to improve their basics.
Mao, Caroline Zhang, and Mira Leung (is she still competing?) are skaters that worked to improve their basics, but it's debatable if they will ever be rewarded like they were in the past when the rules were more lenient and they skated to the strengths they already possessed. Has it just been bad timing for Caroline and Mao considering puberty tends to throw things off, especially because technique had just been reworked? It may mainly be a ladies singles issues and I haven't checked the lastest revision of CoP, but it seems to me that tampering with technique tends to be rewarded less often than working the system to suit what you already have working.
