Patterns of synthesis of all the variations of ～とまではいかないが

Question

During my time studying Japanese, I have come across many variations of the ～とまではいかないが (even if not) pattern, which are as follows.

1. ～とまではいかないが

2. ～とまではいかないとしても

3. ～とまではいかないにしても

4. ～とまではいかないまでも

5. ～とまではいかなくても

6. ～とまではいかなくとも

7. ～とまではいかずとも

8. ～ところまではいかずとも

9. ～とはいかないまでも

10. ～とはいかないにしても

I would like to know in the first place if these are all the possible variations of the ～とまではいかないが pattern, as I would prefer to discover and learn them all at once and not in dribs and drabs as till now.

Besides, I have tried to compress all these variations into a few patterns in order to have a simpler, but at the same time complete structuring of all these variations in my head.

～｛とは・とはまでは・ところ（は）・ところ（は）までは｝いかない｛が・としても・にしても・までも｝

～｛とは・とはまでは・ところ（は）・ところ（は）までは｝いかなく｛ても・とも｝

～｛とは・とはまでは・ところ（は）・ところ（は）までは｝いかず｛ても・とも｝

Would these patterns of synthesis of all the variations of ～とまではいかないが be correct and complete?

If possible, I would like you to help me to correct and modify them as necessary so that they collect all the variations in the simplest possible way.

Answer 1

These expressions (1 to 10) are all correct, but you've "compressed" them incorrectly.

• とはまでは and ところはまでは are wrong. Why use two contrastive は's?
• ところはいかないが is wrong. You have to use まで and say ところまではいかないが.
• いかずても is wrong. This must always be いかずとも.

Also note that these can be easily split into more basic rules and patterns, and I can easily think of many other variations including とまでいかないにしたって, とまで言うわけでもないが, とまではいくといえなくとも, とまでじゃなくても and とまでは言わねど. I felt the same thing when you asked this, but there are countless combinations, so you should stop trying to "compress" them halfway and memorize them all.
