Yes.

Yes.

There are variables that would determine whether this series is successful:

• The quality of the ideas
  
• The detail you go into
  
• The way you present it
  

Should you be able to constantly meet a high standard then by all means go ahead, judging by the diamond count here people seem to be interested.

I also wouldn't recommend making one giant blog, people will probably lose intrest fast. Take my Minedeas for example. My blog was so long it went well over double the character limit(my tl;dr section went over 500 words), so I had to make it an image to fit. I highly doubt anybody really read more than the first idea or two.

If I had of made it a series I would have been able to go more in depth and I would have probably had more views and I could have linked to all my other blogs, therefore giving my series more exposure.

I really have to learn to be more concise...

A series of blogs might not be the best of ideas, due to it being inefficient and time costly. A better plan would be posting a single blog pertaining to the topic, then adding onto that blog as you come up with new ideas. That way you'll be able to do so at an accelerated rate and still be able to occasionally post your concepts.
