I have the little IR filter sitting in front of me right now and I was thinking of maybe putting it back just to see if there is any loss of IQ from the original (i.e. to answer the question, "Is it 100% reversible?"). My guess is that the answer is yes but I have not been protecting the IR filter, it's just sitting on the table and may be scratched (I made no attempt to protect it). Note that the IR filter is not scratched during removal. It just sits there on a little rubber gasket. It's not like it has to be removed with tweezers like replacing a focus screen on a dslr for example. Any scratching of the IR filter would take place from being moved around on the table (because I took no measures to protect it thinking I would never use it again).
IIRC some users who removed the IR filter in the past reported focus problems that required additional adjustment. One example https://chdk.setepontos.com/index.php?topic=12625.0
There also may be significant chromatic aberration in IR, since the lens was designed on the assumption it would be filtered out.
In any case, nice work and thanks for the additional description.
