You should be able to include the team in India amongst the professionals you manage if the benefit of the work flows to the corporate collective. You don't have to be outside the USA for three years. The required time period is one year. This could work, but you must have a detailed consultation with your lawyers. They should make sure your proposed jobs in India and then in the USA meet the legal requirements for an L-1A/EB-1C.

 Unless you have a specific job in hand, the one that has been described in the H-1B you should not come back.

a). Although you entered the United States on advance parole this time you are still considered to be holding a H-1B status. That is not disturbed by your exit and entry.

b). The I-94 that you get with the advance parole entry is limited and hence it should not be a problem. You should be able to transfer employers. You definitely can amend or even extend your H-1B within the United States. I am not aware of any limitations on the ability to use the H-1B for a transfer.

c). Yes you can always revive an H-1B. If the H-1B has expired, you can seek a renewal of the H-1B through the USCIS and then go outside the USA (your home country or any country) and get a H-1B visa stamp and come back.

The problem I see is that the approval is too old. A never-used H-1B approval obtained more than six years ago may not be viable. But, you can have it researched further. I suggest you look into something called the” remainder option.” Although, it is probably not applicable to you, but your lawyers should make sure of that.  Normally, the remainder option is available for people who were employed for a while in the USA on H-1B. These folks, if they go outside the United States for one year after the H-1B employment, can get the time remaining on their H-1B without regard to when it was approved.

I do not see any problem because remember there is the possibility of self-portability as well. But of course, you should have your lawyers review the two job descriptions and make sure they are same or similar.

 Firstly, talk with your DSO. Second thing is to talk to your congressman's office. Even though they are effective in my opinion they can take time. These are the only two steps that I can recommend in addition to what you have done.
