Theory to "Brute force attack rule-based" OR "Attack hybrid dictionary/rules"

I have a problem regarding custom rules what I need is simple but it does not know if it's possible because currently the Hachcat v.0.47 is not supported, and come to the problem.

Need to create rules so

Example 1

i6?d?u i7?d?u i8?d?u i9?d?u
i6?d?u i7?d?u i8?d?u i9?d?u iA?d?u
i6?d?u i7?d?u i8?d?u i9?d?u iA?d?u iB?d?u
i6?d?u i7?d?u i8?d?u i9?d?u iA?d?u iB?d?u iC?d?u
...

However is not supported by the rules and mask is not possible this way creates.

Only then is supported

What makes the process of creating a Herculean labor rules

It would be possible to have support built-in charsets?
?l ?u ?d ?s ?a ?h ?D ?F ?R
to the rules in the next versions of hashcat?

Would be possible by support masks for the rules?

Is there another way I can create rules both in Example 1 as in Example 2 automated? If there is no way to create automated Example 1, Example 2 is possible in this version of Hashcat?

If not, someone here has a suggestion for how I create Example 2 automated rule?

Is there any limitation on the method that I propose?

Pays to brute force based on rules?

How many percent acceleration impementação we could have with this method?

Just do not want to write a rule Example 2 manually :/

In theory, I want to break the "ualpha-numeric" key, but create "ualpha-numeric" size 7+ wordlist becomes strained by the size of the wordlist to be generated, so with that in mind I want to create the "ualpha-numeric" wordlist size 6 characters and make key with the rest of the rule ( i = insert ) or even make forçabruta exclusively by the rules only doubt i have is offset, if in practice we would have more computational efficiency in the process if the process of making brute force by rules is faster than the classical brute force. But to create the rule to make the rest of the key to be broken the way it currently ta becomes a Herculean task therefore becomes indispensable enhance the rules for support masks (or otherwise ) of the rules .
The unique rules that could benefit from this new method I propose are :

Insert N @ X INX Inserts character at position N

and

Overwrite Overwrites @ N ONX character at postion N with X

But as anybody there who are the geniuses behind the project feel free to create whatever they want I just thank.

I thank any other trick inform
