Give agile a test out for a project and see how you get on with it. Once you get into the mindset its not that hard to go with. four devs is fine for agile, its about the size of teams we had in coursework assignments.

Our course introduced the concepts in a 'fun' way by having tasks done through the agile method which had nothing at all to do with programming so it might be an idea to run a mini-workshop to get people into the way of thinking

Things like cards with numerical challenges, card pyramid building, card sorting, balloon tying etc etc etc
Each challenge card had its 'business value' written on it and you assign a complexity to them from 1-5. you then divide business value by complexity and order them in descending order. You agree acceptance tests with whoever is organising the workship and then you then get through as many of these tasks as you can in a fixed period of time. After the time is up you get more tasks given to you and you use the experiance of the last 'sprint' to reassign complexities to tasks and work from there again
The idea is to get as high a resulting total from b.value/complexity as possible at the end of a few sprints
