Is it allowed in the riwayah of Hafs to lengthened al medd al muttassil to 6 harakaat when stopping on a word (that contains a medd mutassil)and thus making it a medd 'aarid li sukoon as in surah 3 aayah 5?

Title: Al medd muttassil

Assalamu aleikum

In the recitation of Hafs by way of Shatibiyyah, the medd al muttassil is lengthened 4 or 5 harakaat. My question is as follow:

Answer
Wa alaikum assalaam wa rahmatullahi wa barakaatuh,
is lengthened four or five vowel counts in the way of Hafs 'an 'Aasim by the way of Ash-Shaatibiyyah. 
is lengthened two, four, or six vowel counts. 
There are times when stopping on a word when we have two reasons for the lengthening of a particular medd letter.  An example of this would be when stopping on the word: .  The conditions for are met, since there is a medd letter followed by a hamzah in the same word.  At the same time when stopping on this word the conditions for  are met since we have a medd letter followed by one voweled letter and we are stopping on it with a conditional (temporary) sukoon. 
When we have two different types of mudood sharing the same medd letter we have to look and see which medd is stronger.  To do this we have the lines of poetry:

 From these lines we see that (the joined) is stronger than but this is not an unconditional rule.  We need to look at the vowel counts involved in each of the mudood according to our methodology when reading.   If we are reading with four vowel counts or five vowel counts, and two vowel counts, then ignore and only use , so when stopping on the word with this methodology in our mudood we would be solely be using .

If we are reading four vowel counts in our reading and with four vowel counts and we stopped on this word, we could only stop with four vowel counts and in this case we would have both of these two mudood being employed. 

If we are reading five vowel counts and four vowel counts we can only stop on this word with five vowel counts, since it is stronger and would solely be stopping with .

If however, we are reading four or five vowel counts in our reading at a particular sitiing and we are stopping on all with six vowel counts, then we can only stop on with six vowel counts, employing as with the six vowel counts it is acting like which is the stronger. of the two.  
Note:  We will only stop on the word with six counts if all our medd 'aaridh are six.  We are stopping on this word then with not . 

Insha' Allah this is clear.  If there are any further questions on this subject,  please feel free to ask.
Ameen to your dua'.  Baarak Allahu feekum.
