Altcoin marketplace - index topic?

[TheButterZone]

Would it be OK for each user to make an index topic, where their altcoins are listed in the subject line, and the URLs to their locked topics are provided in the body, so only the index topic can/needs to be bumped?

My index topic would include:
https://bitcointalk.org/index.php?topic=2133766.0
https://bitcointalk.org/index.php?topic=2106791.0
https://bitcointalk.org/index.php?topic=2106325.0
https://bitcointalk.org/index.php?topic=1989377.0
https://bitcointalk.org/index.php?topic=1980680.0
https://bitcointalk.org/index.php?topic=1913090.0

Or...
They could be merged, with each topic becoming its own post within a single topic, but each post wouldn't be able to be broken off & archived for preservation & decluttering the merged topic, once sold...
