I'm gonna say no, not really. One of the benifits to using the mecate is the wieght and feel to it. With the heavey rope you get a presignal in the hackmore long before you ever make contact with the hackmore nose band. That is what you are going for with the hackmaore set up. if you try to muscle the hose with a rawhide hackamore it will not work. You are using it to teach the horse off of the signal and not nesicarilly from the contact and pressure. With the macate you have weight and the knot on the under side is actually used as a signal as well. The extra lenght is just that, extra lenght. it doesn't really serve a propose for communication but it does come in handy when dismounted at gates or what ever. I usually just tuck it in my belt and off i go. Occasionally I will wrap it with a half hitch around the horn but I just like having in my belt most of the time.
As for the lairat rope, I wouldn't use it either. First lariat rope is usually pretty stiff and the knot would be pretty tough to tie right. Also the lairat rope is considerably thinner than a mecate rein so you don't really have the "feel" as i said earlier. Most bosals that you use on horses that haven't ever been used with a bosal set up are usually 5/8ths inch thick. The mecates are usually about the same. The thinner bosals or bosalitos or pencil bosals are thinner but they are for horses that are more versed in the hackamore or even if the rider is using the two rein to move the horse into the spade bit for a true bridle horse. They are also used as a nose band to lead the horse so you aren't leading a horse with the bridle reins. Again with a mecate tied but different than if using it as reins.
If you were set on making your own Mecate , it can be done. Go to a hardware and get 22-24 ft of good marine rope. it is pricey but it will work. I've even seen people use a good hemp rope to get alittle more bristley feel like the horse hair but I don't really like that. it may work for you though. Hemp feels alot more roough to me and it gets old and dry rots and breaks.
