"Partial" Upgrades: A Possibility?

[timc2011]

Given the competing demands (i.e. developing new programs, versus upgrading old ones), is there an efficient way to produce "partial" upgrades, at least of the existing 4G scripts?

From what I have read, it appears that a main feature of the 5G upgrades (by no means the only one) involves the Optimus Engine, which appears to be a meta-script superimposed upon the main script for each program, that which addresses the issue directly or concern. This is likely waaaay oversimplified, but my thought was that a generic version of the OE, possibly together with other technical features introduced into 5G programs (devoid of content-specific references), superimposed onto the existing 4G script might be a time-efficient way to impart some enhancements. Obviously, the supposition I'm making is that the form of the OE is severable from the content of the program, and that it's likely honed on focusing the attention (intention) of the listener on the substantive content of the program script, whatever it is. Again, I could have things utterly misconstrued here, but just an idea ....
