Could the Temple have built PICAs without a 240 hour time limit? Yes, but I doubt they'd have had the inclination or imagination to do that.
IIRC those limits were built in at a fundamental level to the PICA OS, and it took a top level programmer at the very top of his game AND desperate situation to get around them [and there were side effects]
Therefore the temple angels may just not have had the skill/capability to do that - or maybe even the awareness it was just about possible.
